SIP Panel Extensions

A Structural Insulated Panel (SIP) is made from a sandwich of two layers of stressed skin and one layer of insulation. The stressed skin layers make it exceptionally strong, whilst producing thinner overall wall thicknesses than other forms of construction. With no need for cavity or internal insulation, structural insulated panels can provide a very fast way of constructing very efficient walls with u-values as low as 0.15, without additional insulation.

SIPs are a very flexible product and can be used with any external cladding, be it brick, render, weatherboarding or metal cladding. Equally they can be roofed with slates, tiles or metal roofing. Internally they can be simply finished with plasterboard and a skim coating (with service cavities where needed) meaning that wet trades are kept to a minimum, speeding up build times even further. They are suitable for new builds and home extensions as well as being ideal in-fill panels between other structures like steel or oak frames

SIP Panel Extensions

A Tried & Tested Solution

SIP Panel Extensions were first developed in America in the 1930’s and have been widely-used in the UK since the 1980’s. They have a proven track record of performance and testing, and have a C.A.T.G. SIP Mark Scheme. The Building Research Establishment, an independent testing body, have produced an Information Paper (IP 13/04) on structural insulated panels and have conducted testing on SIPs on behalf of the Government and insurers.
